ABSTRACT:
A speed-responsive engaging mechanism adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of cam surfaces thereon formed in apertures in the discs with a series of friction shoe assemblies mounted in the apertures in engagement with the cam surfaces. The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the cam means induces a wedging engagement of the shoes with the impeller member. Spring means are provided to retain the shoe assemblies in the apertures, and a roller mechanism is provided in each shoe assembly to provide relatively frictionless relative movement between the cam surfaces and the shoe assemblies. Means are provided in the apertures which in cooperation with the spring means, tilt the shoe assemblies to eliminate the viscous drag effect.
